I am looking for a polisher to clean collectible bottles?

I have been commissioned to sell some collectible items and old bottles are among the items. What I am looking for is something that will clean the bottles without changing the value.

maybe a rotary tool that you can change the level of power (such as dremel) with just a microfibre cloth put over a hard foam rod shaped wand(if they even make those)–might have to make your own
I have read several websites investigating an answer to this problem, and they all point to the same conclusions:
-First try warm water with soap (I would suggest being careful to not get the water too warm and use the same temperature for rinsing or the temperature difference could cause the glass to shatter)
-Use Lime Away (or CLR) for mineral and other deposits that aren’t easily removed. They are readily available in most stores, and they are used on expensive clear glass shower doors.
-Lastly, a few sites recommended the use of a mixture of one part water to 3 parts white vinegar as a cleaning agent in place of Lime Away. Since vinegar is mildly acidic, it will break through many deposits, be less corrosive on your hands, cheaper in price, and provide a nice shine to the glass since it is the base for most glass cleaners.
